  System.out.println(myVector); 
  System.out.print("Is myVector empty ");
  System.out.println(myVector.isEmpty());
  
  /*Add Elements to myVector*/
  myVector.add(10);
  myVector.add(11);
  myVector.add(12);
  myVector.add(10);
  myVector.add(12);
  
  System.out.println("\nElements in myVector");
